Criminal Defence

For all of his career Marios has been instructed in cases of the utmost seriousness including cases where the liberty of company directors were at play and that involved an international dimension. This has included the initial ‘Iraqi’ hijacking trial where detailed arguments in respect of the defence of duress of necessity, the concepts of ‘immediacy’, ‘proportionality’, the Nuremberg Convention and other treaties governing crimes against humanity were fully argued both before the Crown court and later before the Court of Appeal.

He has both been led and dealt with cases as a leading junior (prior to taking Silk) in cases ranging from riot to drugs importations and murder. This has included cases where it was alleged the criminal conduct was to raise funds for Al-Quaeda. He was also instructed in what was at the time the largest re-insurance fraud in British history and has acted as Special/Independent Counsel in matters pertaining to disclosure involving professional individuals and potential criminal offending.



Marios represented the interests of a senior consultant in the Crown Court convicted of a fraud against his employing hospital over many years. Despite the loss initially being placed at over £40,000 Marios succeeded in securing the doctor a suspended sentence.

R v V & Others

Marios defended in an Serious Fraud Office (‘SFO’) prosecution, involving a multi-million pound international re-insurance fraud, which raised issues. The case encompassed areas such as European Directives, public and private international law, conflicts of law together with the specialised and complex areas of enforceability, implied actual authority, ostensible authority and ratification. SFO elected not to proceed at trial following defence submissions on the law.

R v H & Others

Marios appeared as junior counsel for one of the Iraqi men accused of hijacking a plane from Jordan to the United Kingdom in order to escape the Sadam Hussein regime in which he feared death. At the time this was only the second ever hijacking case in English history and Marios was the youngest of all the counsel instructed. The case involved legal arguments on the defence of necessity, crimes against humanity and the Nuremberg Convention.

R v Dr A

Marios defended a general practitioner in the Crown Court accused by five separate female patients (unknown to each other) of sexually motivated and inappropriate examination and touching of their breasts. Despite the Crown calling expert evidence that all these examinations were not clinically justified or appropriately executed, including for the one patient that attended for an in-growing toenail, the doctor was acquitted of all the allegations.

CQC v Corporate Entity & Another

Marios defended a company and one of its individual directors operating an exclusive ‘detox’ retreat used by many stars and celebrities. The CQC issued criminal proceedings in which it alleged a multitude of regulatory breaches against both the corporate entity and the individual director (who was also separately registered with another regulator). Marios advised and negotiated a settlement on behalf of the defence.

R v S

Marios defended a young mother accused of trying to kill her own child whilst in the throws of a psychotic episode. The case involved detailed legal argument and expert evidence.
